By 1946, the Yakovlev "Yak-Jumo" project to build a single-engine jet fighter with a reverse-engineered Junkers Jumo 004 engine (dubbed the RD-10) hammered into the existing [[Yak-3 (Family)|Yak-3]] fuselage was well underway, but a few setbacks meant that the full production variant, the [[Yak-15]], could not be fully produced in the required numbers for the October Revolution Air Parade on November 7th. As such, a special variant was quickly ordered for the parade, with much of the unnecessary/untested parts being left out to save time. As such, this special Yak-15 was missing the armour plating and quite a few instruments and avionics, and these aircraft were not even fitted with guns. Some planes had extra fuel tanks installed where the missing guns were supposed to be. Finally, these 15 aircraft were given a bright-red paint scheme for the parade. To save time as the program was already behind schedule, shortly after the parade two of these aircraft were quickly fitted with armour and a single [[NS-23 (23 mm)|NS-23]] 23 mm cannon to begin state acceptance trials.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Russian jet fighter {{Battle-rating}}. It was introduced in [[Update 1.31]].

The Yak-15 is arguably one of the most underestimated planes in the game. Although its stat card reveals what would be considered "sub-par" performance and armament, the Yak-15 is both a unique and deadly fighter. Unlike its propeller-driven counterparts, this first generation jet aircraft wields the ability to hold on to energy in a straight line, whereas prop aircraft will slowly lose speed. Holding speed coupled with its excellent rate of turn allows the Yak-15 to defend itself against both propeller and jet-powered fighters, which is what it will typically face in all game modes.
+
It is also worth noting that the "Yak-15P" designation never actually existed, only being used unofficially many years later to differentiate the special first 15 rushed aircraft from proper production Yak-15s, and it is unknown whether the P in Yak-15P stands for "Parade" or "Pre-production".
  
−
The Yak-15P's major faults include a low top speed, poor acceleration, little armor protection, and small ammunition pool which collectively make this aircraft harder to use than even other first generation jet aircraft such as the [[He_162_A-2|He 162 A-2]], the [[Meteor_F_Mk_3|Meteor F. Mk.3]], and the [[F-80A-5]]. Although it is driven by a jet engine, it is important to recognize the faults and oddities within this aircraft series as they are not representative of the traditional "jet fighter" at all. The Yak-15 is most easily viewed as a late-war [[Yak-3]] powered by a jet engine and with a different armament.
+
The '''{{Specs|name}}''', introduced in [[Update 1.31]], is a very peculiar aircraft among all the early jets of War Thunder. Unlike the only other jet in history to be successfully derived and mass-produced from a pre-existing piston fighter, the Swedish [[J21RA|J21R]], the Yak-15P does not sacrifice its familiar flight performance heavily. Instead, the Yak-3P retains its incredible handling characteristics familiar to previous [[Yak-3]] pilots, allowing it to swiftly outmanoeuvre most jet aircraft it faces. The biggest drawback however is the low top speed and horrible compression at high speeds compared to contemporary jets, giving the Yak-15s their biggest disadvantage: high speed engagement. One should be wary of this weakness when engaging multiple aircraft at once, as the Yak-15P does not have the option of escaping when things go south due to its weak acceleration and troublesome controls at higher speeds. The Yak-15P differs from its production variant, the later Yak-15, in its basic gun-play: the aircraft loses one of its 23 mm cannons which results in the aircraft being at a lower battle rating, opening many new doors for it to be used as a CAP/air superiority aircraft in combined battles at battle ratings the normal Yak-15 could not be used.

<!-- ''Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.'' -->
 +
The handling of the Yak-15P is uncomfortable in most situations. For a jet-engined aircraft it has very poor top speed and the acceleration at all states can be considered inferior. With a poor climb rate and weak engine, it is easy to get yourself into hard situations. However, the Yak-15P has a very nimble airframe and good agility in dogfights, and its weak engine is still enough to make it hold speed better than most props in a turn fight.

Obtaining the "Offensive 23 mm" modification is the best choice as it allows for more flexibility in armament. Next, try to obtain the "compressor" and "engine" upgrades as they both increase engine thrust which is essential in escaping from a dogfight turned sour. Finally, obtain the rest of the performance upgrades as they will all collectively increase top speed, turn time, and rate of climb.

In realistic battles, climbing with this aircraft at the start of a match is not always the best course of action, considering how poor the Yak-15's rate of climb is. Instead of the traditional and slow angled climb, the Yak-15 is best used in a "zoom climb" where once enough energy has been built up at a low altitude the Yak-15 pilot will pitch up, thus gaining altitude quickly. This way, if attacked during the first few minutes of the match, the Yak-15 still wields some energy whereas had the Yak-15 been slowly climbing, it would have had to face another aircraft's guns. To shake an enemy, especially a prop driven enemy, dive low to the ground to ensure your assailant's speed only decreases. This dive is called a "speed trap" and is effective when followed by either a "hammerhead" attack or a continuation of the escape. This tactic of utilising the Yak-15's ability to hold on to energy in a straight line is negated when facing other jet aircraft who wield the same ability; however, this is where the Yak-15's dogfighting abilities come into play. Because it is so similar to the Yak-3, the Yak-15 retains some of its manoeuvrability characteristics, namely its turn time. This facet often proves an indispensable one as other first-generation jets will not be able to maintain a tight enough turn circle.

However, the Yak-15P is '''severely''' hampered in its damage output due to its reliance on a single  23 mm NS-23K cannon, with 60 shells total. Expending this pool in seconds is possible. The Yak-15P shares this downfall with aircraft like the [[Ki-200|Ki-200]], and the [[Me_163_B|Me-163]]. Firing in small, accurate bursts negates this and is the most efficient way of destroying enemies. The 23 mm shells these cannons fire are extremely deadly when they hit and often rip enemies apart.

To use the guns most effectively, be close to your target. The reason for this is twofold: First, the limited ammo means you want your shots to count. Being close to your target will give your cannons the highest chance of hitting. The second reason is that of the ballistics of the 23 mm shells - their muzzle velocity is not very high, meaning you have to lead your targets by quite a bit. If you are closer to your mark, you won't have to lead them by quite as much, although still more than most other cannons.

With some practice, it is possible to consistently get about two fighter kills with one load of ammunition in realistic battles. Using the Air Targets belt is the most effective. However, attacking bombers is best left to other planes with more firepower, since the Yak-15 does not have the firepower or ammunition to kill heavy bombers without sustaining massive damage reliably. Heavy fighters such as the [[F7F-1]] may also take longer to destroy than other opponents.

Its development started at the end of World War II, when the Soviet Union captured numerous German components, including Junkers Jumo-004 jet engines. This engine was studied in the USSR, and the Klimov OKB created a domestic counterpart under the designation RD-10. In turn, the Yakovlev OKB used the design to produce a jet fighter based on the latest version of the well-liked Yak-3.

Nevertheless, the significance of the Yak-15 in the history of Soviet aviation should not be underestimated. Hundreds of pilots underwent training on planes of this type, and it was the Yak-15 that became the first Soviet jet aircraft officially accepted for service in the Air Force as well as the first jet fighter that enabled military pilots to master advanced aerobatics.

Description

By 1946, the Yakovlev "Yak-Jumo" project to build a single-engine jet fighter with a reverse-engineered Junkers Jumo 004 engine (dubbed the RD-10) hammered into the existing Yak-3 fuselage was well underway, but a few setbacks meant that the full production variant, the Yak-15, could not be fully produced in the required numbers for the October Revolution Air Parade on November 7th. As such, a special variant was quickly ordered for the parade, with much of the unnecessary/untested parts being left out to save time. As such, this special Yak-15 was missing the armour plating and quite a few instruments and avionics, and these aircraft were not even fitted with guns. Some planes had extra fuel tanks installed where the missing guns were supposed to be. Finally, these 15 aircraft were given a bright-red paint scheme for the parade. To save time as the program was already behind schedule, shortly after the parade two of these aircraft were quickly fitted with armour and a single NS-23 23 mm cannon to begin state acceptance trials.

It is also worth noting that the "Yak-15P" designation never actually existed, only being used unofficially many years later to differentiate the special first 15 rushed aircraft from proper production Yak-15s, and it is unknown whether the P in Yak-15P stands for "Parade" or "Pre-production".

The Yak-15P, introduced in Update 1.31, is a very peculiar aircraft among all the early jets of War Thunder. Unlike the only other jet in history to be successfully derived and mass-produced from a pre-existing piston fighter, the Swedish J21R, the Yak-15P does not sacrifice its familiar flight performance heavily. Instead, the Yak-3P retains its incredible handling characteristics familiar to previous Yak-3 pilots, allowing it to swiftly outmanoeuvre most jet aircraft it faces. The biggest drawback however is the low top speed and horrible compression at high speeds compared to contemporary jets, giving the Yak-15s their biggest disadvantage: high speed engagement. One should be wary of this weakness when engaging multiple aircraft at once, as the Yak-15P does not have the option of escaping when things go south due to its weak acceleration and troublesome controls at higher speeds. The Yak-15P differs from its production variant, the later Yak-15, in its basic gun-play: the aircraft loses one of its 23 mm cannons which results in the aircraft being at a lower battle rating, opening many new doors for it to be used as a CAP/air superiority aircraft in combined battles at battle ratings the normal Yak-15 could not be used.

The handling of the Yak-15P is uncomfortable in most situations. For a jet-engined aircraft it has very poor top speed and the acceleration at all states can be considered inferior. With a poor climb rate and weak engine, it is easy to get yourself into hard situations. However, the Yak-15P has a very nimble airframe and good agility in dogfights, and its weak engine is still enough to make it hold speed better than most props in a turn fight.

Obtaining the "Offensive 23 mm" modification is the best choice as it allows for more flexibility in armament. Next, try to obtain the "compressor" and "engine" upgrades as they both increase engine thrust which is essential in escaping from a dogfight turned sour. Finally, obtain the rest of the performance upgrades as they will all collectively increase top speed, turn time, and rate of climb.

  • 1 x 23 mm NS-23K cannon, nose-mounted (60 rpg)

Usage in battles

In Realistic battles, climbing with this aircraft at the start of a match is not always the best course of action, considering how poor the Yak-15P's rate of climb is. Instead of the traditional and slow angled climb, the Yak-15P is best used in a "zoom climb" where once enough energy has been built up at a low altitude the Yak-15P pilot will pitch up, thus gaining altitude quickly. This way, if attacked during the first few minutes of the match, the Yak-15P still wields some energy whereas had the Yak-15P been slowly climbing, it would have had to face another aircraft's guns. To shake an enemy, especially a prop driven enemy, dive low to the ground to ensure your assailant's speed only decreases. This dive is called a "speed trap" and is effective when followed by either a "hammerhead" attack or a continuation of the escape. This tactic of utilising the Yak-15P's ability to hold on to energy in a straight line is negated when facing other jet aircraft who wield the same ability; however, this is where the Yak-15P's dogfighting abilities come into play. Because it is so similar to the Yak-3, the Yak-15P retains some of its manoeuvrability characteristics, namely its turn time. This facet often proves an indispensable one as other first-generation jets will not be able to maintain a tight enough turn circle.

However, the Yak-15P is severely hampered in its damage output due to its reliance on a single 23 mm NS-23K cannon, with 60 shells total. Expending this pool in seconds is possible. The Yak-15P shares this downfall with aircraft like the Ki-200, and the Me 163. Firing in small, accurate bursts negates this and is the most efficient way of destroying enemies. The 23 mm shells these cannons fire are extremely deadly when they hit and often rip enemies apart.

To use the guns most effectively, be close to your target. The reason for this is twofold: First, the limited ammo means you want your shots to count. Being close to your target will give your cannons the highest chance of hitting. The second reason is that of the ballistics of the 23 mm shells - their muzzle velocity is not very high, meaning you have to lead your targets by quite a bit. If you are closer to your mark, you won't have to lead them by quite as much, although still more than most other cannons.

With some practice, it is possible to consistently get about two fighter kills with one load of ammunition in realistic battles. Using the Air Targets belt is the most effective. However, attacking bombers is best left to other planes with more firepower, since the Yak-15P does not have the firepower or ammunition to kill heavy bombers without sustaining massive damage reliably. Heavy fighters such as the F7F-1 may also take longer to destroy than other opponents.

In Arcade battles, the Yak-15P is capable of breaking up a "furball" due to its impressive turn time. The turn time coupled with its hard-hitting cannon makes any Yak-15P pilot an indispensable asset to any Arcade team.

History


Archive of the in-game description

An all-metal, single-seat fighter equipped with a turbojet engine.

Its development started at the end of World War II, when the Soviet Union captured numerous German components, including Junkers Jumo-004 jet engines. This engine was studied in the USSR, and the Klimov OKB created a domestic counterpart under the designation RD-10. In turn, the Yakovlev OKB used the design to produce a jet fighter based on the latest version of the well-liked Yak-3.

The designers decided in favor of the pod-and-boom layout. A turbojet engine with 900 kg thrust was mounted instead of the old VK-107A piston engine. The engine was inclined so that the jet stream exited underneath the fuselage and wing. The rest of the airframe was left almost unchanged, except for an additional heat shield, made of refractory steel, located in the exhaust section. The aircraft's armament included two Nudelman-Suranov NS-23KM cannons with 60 rounds each. The cannons were housed in the forward fuselage above the engine. The new Yakovlev fighter was originally called the Yak-Jumo but later obtained the designation Yak-15.

The first flight of the Yak-15 was on April 24, 1946, and the plane was launched into full-scale production in the autumn of the same year. Production Yak-15 planes had a different engine, the RD-10, manufactured in the USSR. The service life of the earliest engines was officially claimed to be 25 hours, but in reality it was 17 hours at best. Nevertheless, the Yak-15 was very easy to pilot, and its steering was similar to that of the Yak-3, which had been the basis of its development. As a result, it was decided that although the Yak-15 did not meet the requirements of the Air Force for a modern combat fighter, it was perfectly suitable as a transition from prop to jet aircraft.

In addition to its engine's limited service life, the Yak-15 had a number of distinctive disadvantages. The most commonly encountered defects during its operation included hydraulic fluid leaks (through the sealing rings of the landing gear shock struts), the rupturing of rudder control cable threads, and the deterioration of tail wheel springs (probably caused by overheating). But the Yak-15's main disadvantage was its very short flight range.

Nevertheless, the significance of the Yak-15 in the history of Soviet aviation should not be underestimated. Hundreds of pilots underwent training on planes of this type, and it was the Yak-15 that became the first Soviet jet aircraft officially accepted for service in the Air Force as well as the first jet fighter that enabled military pilots to master advanced aerobatics.

Production of the Yak-15 was discontinued in 1947. In all, 280 planes were constructed.
